TO ALL WHOM IT MAY CONOERN: y

'Be it known that I, HERMANN BERG, of Springfield, in the county of Hampden, and State of Massachusetts; have'invented a new and useful improvement in Rocking-0hairsg and I do hereby declarethat the following is a full, clear, and exact description thereof, which will enable these skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure 1 represents a longitudinal vertical section-of this invention.

Figure 2 is a perspective view of the same.

Similar letters of reference in both views indicate corresponding parts.

This invcntionconsists in' a rocking-chair the frame of which isV composed of two side-pieces which are made of thin and elastic strips of metal or wood, and united together by cross-bars which can be readily removed, if desired, in such a manner that 'a chair is obtained which is very comfortable and easy to sit in, and whichlcan be easily packed up in a comparatively small compass for transporta-tion. The side-pieces of the frame are so' constructed that each-runner, with its arm-piece, is formed out of one strip, which is curved and secured to another strip, forming'one-half of the back frameand one of the hind legs ofthe chair, and suitable stops are secured in the runners in front and rear, whereby the chair is prevented 'from being' tipped over in either direc-A tion. Said stops consist of buttons secured to springs, whereby the same are rendered yielding, and hard blows or shocks in stopping the mo-tionsof the chair are avoided. The back of the chair is formed of a piece of stout cloth, canvas, leather, or other liexible material, which extends from under the seat up to the top cross-bar, and which is so adjusted that it forms a comfortable curve to supportv the person sitting,r in the chair, and that the centre of gravity will be in the proper relation to the runners. i

A represents a rocking-chair, the frame of which is composed of two side-pieces, B C. These sidepieces are formed each of two flat strips, lib e e', of elastic sheet metal, or ofttough wood or other suitable elastic material, which are curved in such a manner. that the strips 6 c form the runners and armpieees, and the strips b c the sides of the back frame and the hind legs, and these latter strips are curved in such a manner that they support the former, and that a chair frame is obtained which is light and elastic in all its parts; The two Side-peces of the frame are united by cross-bars, a al a2, which are provided with nuts at one or both ends, s0 that by taking off said nuts the rods can readily be removed whenever it maybe desired to pack up the chair in a small compass for transportation-or other purposes. The cross-bars al have their bearings in arched-strips', d, which are secured between the strips Z) and c c', as clearlyshown in the drawing, and these cross-bars'scrve to support the seat D, which is curved in the proper manner. vThe back E is formed of a piece of stout cloth,

canvas, leather, or other suitable flexible material, which extends from under the seat D up to the top cross-bur al, and which is so adjusted that it sags down and forms aconifortable support for the person sitting in the chair. This flexible back can also be readily adjusted by unfit-sterling one of its ends, and giving to it more or less slack, or one end may be secured to a rod which may be so adjusted that by turning the same the back receives more or less slack, and by these means said back can be easily brought in such a vposition that the centre of gravity of the person sitting in the chair is thrown in the proper relation towards the runners, a point which is of the greatest importance in a goed rocking-chair, for if the centre of gravity is too farn front, the person sitting on the chair is vliable to slide down from the seat, and if the centre of gravity is too far in the rear, the chair-'is liable to tip over behind,'or at least to-assume an uncomfortable position. At or near the ends of the rockers of my chair are secured the stops e, which are composed of buttons which are so placed that they coniine the oscillating motion of the chair within certain limits, and prevent the chair being tipped over accidentally, either backward or forward. The buttons e pass through holes in the rockers, and they are secured to the loose ends of springs,f, which are fastened to the inner surfaces of the rockers, and whichrender the stops yielding, so that incase one of them strikes the floor, a hard blow or shock isA avoided, and the rocking motion of thc' chair is stopped gradually. By these .means a-chair is obtained which is light, cheap, very comfortable, and easily packed for transportation. i

What I claim as new, and desire to secure by Letters Patent, is-

1. Constructing' thesidc frames of streaking-chair of elastic strips,1 7) c c', substantially as and for the purpose set forth.

2. TheA combination of removable cross-bars a al az, with the elastic sdidelpieees B C of a rocking-chair, substantially as and for the purpose described. i l

3.V The eXible bock E, in combination With-the seat D. top cross-bar a1 :md side-pieces B C, constructed and operating substantially as and for the purpose set forth.'

4. The yielding stops e, in combination with the .runners of a rocking-eheh, constructed and. operating substantially as and for the purpose described.
